Areas Of Concern

As manufacturers shift their focus from selling products to providing services, designers must therefore increasingly consider the life-cycle requirements in addition to conventional design parameters. To identify possible areas of concern, engineers must consider knowledge gained through the life cycle of a related product. However, because of the size and distributed nature of a company’s operation, engineers often do not have access to front-line maintenance data. Additionally, the large number of documents generated during the design and operation of a product makes it impractical to manually review all documents thoroughly during a design task. This paper presents a prototype knowledge-based document repository for an aeroengine manufacturer. The developed system searches and analyzes distributed document resources, and provides engineers with a summary view of the underlying knowledge. The aim is to aid engineers in creating design requirements that incorporate maintenance issues. Unlike existing document repositories and digital libraries, our approach is knowledge based, where users browse summary reports instead of following suggested links. To test the validity of our architecture, we have developed and deployed a prototype of our knowledge-based document repository. The repository has been demonstrated to and validated by the engine design community.

Support Engineering

Manufacturers are currently shifting their focus from selling products to providing services, hence the product’s designers must increasingly consider life-cycle requirements, in addition to conventional design parameters. To identify possible areas of concern, engineers must consider knowledge gained through the life cycle of similar or related product. However, because of the size and distributed nature of a company’s operation, engineers often do not have access to front-line maintenance data. In addition, the large number of documents generated during the design and operation of a product makes it impractical to manually review all documents thoroughly during a task. This paper presents a knowledge-based document repository demonstrator that is capable of providing such support for the maintainers and designers of jet engines.

Design Requirements

This paper develops a general framework for knowledge-based computer tools that promote simultaneous engineering in mechanical design. Design compatibility analysis (DCA) serves as the underlying concept for these knowledge-based systems. DCA focuses on the compatibility between the design requirements (specification) and the proposed design, evaluates the design based on the compatibility knowledge of experts, gives justifications for the evaluation, and suggest improvements. DCA accommodates a product's various life-cycle issues (e.g. functionality, manufacturability, reliability) with a unified focus, i.e. compatibility, and thus helps designers to incorporate these issues at the early stages of design (simultaneous engineering). The resulting framework not only serve as the basis for various design expert systems but will also enhance our understanding of the life-cycle design issues. We illustrate the proposed method with two examples: system design of power generation plants and design for assembly (DFA) of mechanical products.

The process of reviewing test data for anomalies after a firing of the Space Shuttle Main Engine (SSME) is a complex, time-consuming task. A project is under way to provide the team of SSME experts with a knowledge-based system to assist in the review and diagnosis task. A model-based approach was chosen because it can be adapted to changes in engine design, is easier to maintain, and can be explained more easily. A complex thermodynamic fluid system like the SSME introduces problems during modeling, analysis, and diagnosis which have as yet been insufficiently studied. We developed a qualitative constraint-based diagnostic system inspired by existing qualitative modeling and constraint-based reasoning methods which addresses these difficulties explicitly. Our approach combines various diagnostic paradigms seamlessly, such as the model-based and heuristic association-based paradigms, in order to better approximate the reasoning process of the domain experts. The end-user interface allows expert users to actively participate in the reasoning process, both by adding their own expertise and by guiding the diagnostic search performed by the system.

Purpose Although there have been a considerable number of studies regarding subsidiary role typology in multinationals’ management literature, there appear to be few studies that consider knowledge-based role typology from the network-based perspective. The purpose of this study is to fill this gap and extend the study of Gupta and Govindarajan (1991). Thus, the study focuses on answering the following research question: Do subsidiaries have different roles in terms of knowledge flows within a multinational company (MNC)? Design/methodology/approach This empirical study has been carried out as an explorative single case study. An MNC with 15 foreign subsidiaries headquartered in Turkey, which operated in the manufacturing of household appliances and consumer electronics, has been selected as the case. Knowledge transfer is analyzed in this MNC from the network perspective. Findings Four role typologies are detected for subsidiaries of the MNC: collector transmitter, collector diffuser, converter transmitter and converter diffuser. Research limitations/implications Findings of this study are specific to this case. Testing the findings in a sample consisting of subsidiaries of MNCs producing transnational products may contribute to the generalizability of these roles. Practical implications This study offers potentially important findings for MNC managers to use. First, in this study, knowledge flows' route could be defined within MNCs’ dual network. Second, role typologies could inform MNC managers to design their MNCs’ knowledge network. Originality/value The suggested typologies are expected to more accurately define the roles of subsidiaries within contemporary MNCs which are accepted to be transformed from hierarchical structures to network-based organizations.

Steam Drum

Process plant industries have equipment working on high pressure and high temperature environments. The ASME Boiler and Pressure Vessel Code, Section VIII provides rules for construction of the pressure vessel. The purpose of this paper is to have comparative study for design and analysis of steam drum using ASME Section VIII Div. 2 and Div. 3. Steam drum is a part of boiler system and works at high pressure and high temperature. Normally, Steam drum design is based on ASME Section VIII Div. 2, Part 4, design by rule and Part 5, design by analysis; which has been carried out in the present study. In this paper, design of the same equipment is studied using Part KD, Design requirements of ASME Section VIII Div. 3 with similar design parameters. Finite Element Stress Analysis of both design has been done as per code requirements to check the plastic collapse. In this study, it is observed that there is reduction in the required thickness for design based on Div. 3. Finally, the reduced required thickness leads to considerable weight reduction of the equipment and thus increased competitiveness.

Abstract A product’s architecture affects the ability of a company to customize, assemble, service, and recycle the product. Much of the flexibility to address these issues is locked into the product’s design during the configuration design stage when the architecture is determined. The concepts of modules and modularity are central to the description of an architecture, where a module is a set of components that share some characteristic. Modularity is a measure of the correspondence between the modules of a product from different viewpoints, such as functionality and physical structure. The purpose of this paper is to investigate formal foundations for configuration design. Since product architectures are discrete structures, discrete mathematics, including set theory and combinatorics, is used for the investigation. A Product Module Reasoning System (PMRS) is developed to reason about sets of product architectures, to translate design requirements into constraints on these sets, to compare architecture modules from different viewpoints, and to directly enumerate all feasible modules without generate-and-test or heuristic search approaches. The PMRS is described mathematically and applied to the design of architectures for a hand-held tape recorder. Life cycle requirements are used as design criteria.

Abstract A knowledge-based Bumper Design System (BDS) has been developed which automatically generates optimized conceptual bumper beams which meet manufacturing and product performance requirement. The BDS has captured and refined the corporate design knowledge of the product design engineer, the CAD designer, the CAE analyst and manufacturer. The BDS enables the bumper design engineers to evaluate multiple design alternatives quickly and early in the design process. It also automates repetitive bumper analysis tasks. The purpose of the paper is to describe the BDS. A description of the Knowledge Based Engineering (KBE) methodology used to create the BDS is given, as well as an overview of bumper designs and design requirements. An overview of the BDS software design, user interface, and a sample run are also presented.

Knowledge Based

This chapter articulates a conceptual framework to analyse the management of environmental sustainability knowledge in tourism that is underpinned by both the knowledge-based view of the firm (Grant, 1996; Spender, 1996) and the KM Life Cycle (Liebowitz & Beckman, 1998; Salisbury, 2012). This deliberate management of knowledge enables NTOs to build a knowledge-base about the natural environment and to use that knowledge for environmental sustainability, business sustainability, and local community education. Ten NTOs in Australia, Malaysia, Thailand, and Vietnam were investigated to analyse their KM of environmental sustainability. In supporting the knowledge-based view and KM of environmental sustainability knowledge, a further conceptual framework is also advanced for the analysis of how Information Technology enables environmental sustainability knowledge to be created, captured, shared, and applied at NTOs among their staff, customers, and communities.
